Key Performance and Signaling Details

• The link runs at 750 KBaud and moves up to 2000 Link Units per second.
• One Link Unit equals one parameter read or write per second.
• Each I/O Link supports a maximum of 40 I/O Units at 50 ms CEE.
• IOTA address jumpers carry numbers 1 to 40 for clear link addressing.
• The cable works as a passive assembly, so it adds no active electronics to the link.
• Cable A (yellow label) and Cable B (green label) always form a redundant pair.
• Honeywell sells each cable individually or as a matched pair.

Installation Guide

• Plug the pre-terminated ends into the C300 Controller IOTA IOL1A/B or IOL2A/B ports.
• Route the cable to Series C IOTAs or IOMs inside the CCA.
• Use the extension cable to reach another cabinet side or a gap without IOTA connections.
• Keep the total extension run at or below 30 ft (9 m) per grounding rules.
• Match the yellow label to the Cable A port, and pair it with the green Cable B.
• Check IOTA address jumpers (1 to 40) before you power the link.
• Follow R301.1 Series C System Cabling rules for cabinet grounding.
